    Very advanced program that is absolutely free, only downside is that it's not as lightweight as SAI

    Both Krita's brush system and UI are very different from SAI, notably the color blending system which make it impossible to recreate the watercolor effect in SAI, it is more similar to Autodesk Sketchbook.

    It has many capabilities, and I've seen people's work using this. It's amazing to work in and is good in animation features.

    Firealpaca is much easier to use! It's simpler to find your way around and it's completely free for mac and windows! It's also great because it has regular updates so you know it's always gonna get better. You can animate on it and use masks, references and palettes.

    The app is very functional :) So many brushes and options. Maybe at the beginning everything's a bit complicated, but if get used to it it's very easy and effective. Also there's a chance of learning so many methods and styles of drawing by the new features and even from other artists. I definitley recommend this aplication :3

    It's like medibang, but you don't have good stabilization and stuff like that. it's a simular.

    Has a lot of features and the ones that are locked can be all unlocked at once if you watch one add, really good alternative but sadly it's only for phone users
